Solution
1. Preparation
  • Gather necessary tools and parts.
  • Disconnect the negative battery terminal to prevent electrical shock.
  • Ensure the vehicle is on a level surface and the ignition is off.
2. Inspect the Fuse
  • Locate the fuse box, typically found under the dashboard or in the engine compartment.
  • Remove the windshield wiper fuse using a fuse puller or pliers.
  • Inspect the fuse for continuity; replace it if it is blown.
3. Test the Wiper Motor
  • Reconnect the negative battery terminal.
  • Use a multimeter to check the wiper motor’s power supply.
    • Disconnect the motor connector and probe the terminals with the multimeter.
    • Turn on the wiper switch and measure voltage (should be approximately 12V).
  • If no voltage is present, check the wiring and switch.
4. Replace the Wiper Motor (if necessary)
  • If the motor is faulty, remove it by:
    • Disconnecting the electrical connector.
    • Unscrewing the mounting bolts (typically 2-4 bolts).
    • Carefully removing the motor and linkage assembly.
  • Install the new motor by reversing the removal steps and ensuring all connections are secure.
5. Reassemble and Test
  • Reattach the wiper arms and ensure they are correctly positioned.
  • Reconnect the negative battery terminal.
  • Turn on the ignition and test the wipers for proper operation.
  • If washer fluid is also non-functional, check the washer pump and fluid lines.
